Fotios "Freddy" Geas, 51, is being eyed as a suspect for allegedly instigating a group of men to beat 89-year-old Bulger to death just hours after he transferred to the USP Hazelton, according to The Boston Globe.

A Federal Bureau of Prisons official told The New York Times on Tuesday that Bulger was killed by fellow inmates, but did not reveal any further details.

Sources close to the investigation told the Globe that Bulger's body was beaten and his eyes were nearly gouged out.

Geas, formerly of West Springfield, Massachusetts, is serving a life sentence at the Hazelton federal penitentiary.

He was convicted of the 2003 murders of a Massachusetts mob boss named Adolfo "Big Al" Bruno, and his associate, Gary Westerman, MassLive reported.
